Android: Previously mentioned webapp Slice does a great job of tracking your packages, organizing your purchases, and giving you a complete view of your purchase history—along with any price drops you may be able to claim. Now, the service has unveiled its new Android app to give users with Android devices the ability to take Slice with them anywhere they go.

Slice is still free, and if you're not already signed up, you can sign up through the Android app once you have it installed. When you do install, the app will walk you through connecting the service with your Google account (Slice uses OAuth to do this, so you don't ever give the service your Google password—and you can easily revoke access at any time,) where it'll scan for purchases you've made. If you're like me and keep order and shipping notifications for just about everything, it can take a while.

When it's finished, you'll have a searchable, interactive purchase history that you can dig back through to find something you bought days, weeks, or years ago, and up-to-the-minute tracking information for your packages, order status on anything you've purchased but hasn't shipped from almost any web retailer, and even push notifications when one of your packages has been delivered. Slice even keeps track of your daily deal vouchers and coupons from Groupon, Living Social, and the rest, so they don't expire before you can use them.

As always, if the app misses a purchase you've made, you can always forward the order confirmation to them to have it automatically imported to your Slice account where you can keep track of it, be notified when it ships, and even get notified if the price suddenly drops—so you can contact the merchant for the difference. Slice Mobile for Android is free, and available now at Google Play. Are you a Slice user? Share your experiences in the comments below.
